We have test results that confirm the giftedness and still wonder if our child is really gifted most of the time. The slow processing speed, deriving weird answers to ordinary questions due to unusual thinking processes, illogical fears etc makes us wonder if our child is gifted or if the tester made a mistake with the results.
And then suddenly, there is a spark of brilliance which again convinces us that there should be giftedness behind it - that and the ability to imbibe vast amounts of knowledge in a short period of time and the ability to do certain things that are too advanced for a typical child of similar age.
